Printing "VOID" on labels after adding an RFID object.

Fix/Answer

If after adding an RFID object to a BarTender document, the word "VOID" begins to print on all labels, then the issue is probably related with wrong data being placed on the EPC segment.

The EPC segment of an RFID tag is very strict with what number of hexadecimal characters/bits it needs to encode. As reference:

The EPC segment needs to contain 16 hex characters (for 64 bit values), 24 hex characters (for 94 bit values) or 50 hex characters (for 198 bit values).

To solve the problem the user has two alternatives:

a. Include a value with the correct number of characters in the RFID object.

b. If you wish to encode "custom" data (not following the EPC rules) then you should do so on the "User" segment, instead of the EPC segment:
